SEN0192 DFRobot Microwave Motion Sensor Compatible with Mobile Detection

The microwave motion sensor is a microwave moving object detector designed by the Doppler radar principle. Unlike general infrared detectors, microwave sensors detect the motion of an object by detecting the microwave reflected by the object. The detection object will not be confined to the human body, and there are many other things. Microwave sensors are not affected by ambient temperature, have long detection range and high sensitivity. They are widely used in industrial, transportation and civil devices, such as vehicle speed measurement, automatic doors, induction lights, and parking sensors.

 

Due to the universality of the object detected by the microwave sensor, in the actual life application, another sensor will be used for the targeted detection. For example, the microwave sensor + infrared pyroelectric sensor can effectively judge whether someone has passed, will not be disturbed by the sunlight, the color of the clothing, and will not react to other objects.

 

Product Features

 

This detection method has the following advantages compared with other detection methods:

 

Non-contact detection;

It is not affected by temperature, humidity, noise, airflow, dust, light, etc., and is suitable for harsh environments;

Strong anti-radio interference capability;

The output power is small, which is not harmful to the human body;

Far detection distance;

Support for detection of non-living objects

The directionality of the microwave is very good, and the speed is equal to the speed of light;
